Title: Epoxidation process with zeolite catalysts
Inventor: GREY ROGER A
IPC: C07D303/04
Filed: 1999-09-21
Granted: 2008-04-29
Abstract: The selectivity of an olefin epoxidation process catalyzed by a titanium-containing zeolite is improved by performing the epoxidation in the presence of a non-ionic tertiary amine or tertiary amine oxide additive. For example, when hydrogen peroxide is reacted with propylene in the presence of TS-1 titanium silicalite to form propylene oxide, non-selective ring-opening reactions of the propylene oxide are suppressed when low concentrations of 2,6-lutidine or other substituted pyridines are added to the hydrogen peroxide feed.
Patent CA-2344232-C (CA)
Inventor: WILLIAMS EDNA M
IPC: F02K9/10
Filed: 1999-10-05
Granted: 2008-01-08
Abstract: Castable propellant formulations are provided including reduced toxicity ballistic modifiers that do not adversely increase the sensitivity of the propellant to shock detonation. Failure to adequately control the propellant burn rate often results in unacceptable performance of the propellant. Carbon can act as an effective ballistic, but not to the extent of metal compounds. It has been found that pasting a ballistic modifier, including ballistic modifiers containing lead, in an inert polymer modifies the burn rate of propellants while allowing the use of a reduced amount of modifier to achieve the same desired burn rate modification as the prior art, and therefore creating reduced shortcomings associated with the ballistic modifiers. Accordingly, the use of from about 1 % to about 6 % burn rate modifier wherein the burn rate modifier includes a ballistic modifier pasted in an inert polymer is taught as an effective burn rate modifier in a propellant, in order to provide reduced toxicity means for modifying the propellant burn rate without increasing the sensitivity of the propellant to shock detonation.

Abstract: A Modbus slave device is operable in an agile mode that allows the slave device to automatically in-terpret and respond to first-type and second-type message frames conveyed to the slave device by a master device. The slave device detects a first incoming character of a master query message frame generated by the master device. If the first incoming character is a prompt character for the first--type message frame, the slave device interprets the master query message frame as the first-type message frame. If the first incoming character is not the prompt character for the first-type message frame, the slave device interprets the master query message frame as the second-type message frame. If the slave device is addressed in the master query message frame, the slave device performs the command as-sociated therewith and, if required by the command, gener-ates a responsive slave message frame of the same type as the master query message frame.

Abstract: Methods and system architectures are disclosed for controlling the processing of data packets in one or more routers. Each router stores received data packets in one or more ingress data queues. In a first aspect of the disclosure, packets held in an ingress data queue are processed by the router at a dynamically adjusted packet flow rate. The ingress data queue has a data queue head structure, including a packets-to-be-processed field. The packets-to-be-processed field has a value indicating a selected number of packets to be processed from the ingress data queue in a given processing interval. In this manner, the packet flow rate of the ingress data queue is adjusted by varying the value of the packets-to-be-processed field, based on current operating conditions (e.g., current processor or memory utilization) of the router.

Granted: 2003-12-30
Abstract: An apparatus for receiving a data stream having a plurality of time domain spread spectrum messages in the same frequency channel. Each message is independent, spread spectrally with a unique code and the data stream contains a subset of all known codes. The apparatus finds a specific code and a constant phase shift between the incoming code and a reference code by serially moving the data stream through a shift register (40), subjecting all the shift register outputs to a single expected reference code and accumulating the result for each output using a plurality of accumulators (42). The code and phase shift is indicated by the largest magnitude of the accumulation, above a threshold, generated by circuit (48), corresponding to the shift register output for the correct phase shift betwen the incomming code and the reference. When an integration cycle terminates, the time shift delay increases by the length of the shift register (40). The process continues for all possible relative time shifts and all the reference codes.
